Galena formula

Sphalerite and galena occur in very minor amounts, particularly in Cu-rich footwall mineral zones and as late, cross-cutting veins in association with late shear zones and faults (Table 4.3). Sphalerite and galena also occur as interstitial grains in massive sulfide and adjacent to silicate inclusions..

Galena is a silvery mineral and the most important lead ore. It melts at a low temperature and was first smelted in prehistoric campfires. Thousands of years later, it would be instrumental in creating the first radios and other electronics. Unsurprisingly, it is a stone for transformation and for having an open mind.Galena é um mineral composto de sulfeto de chumbo (II), e o mais importante dos minérios do chumbo e praticamente o único. Cristaliza no sistema cúbico, quase sempre em octaedros. Tem cor de chumbo, com um brilho metálico intenso e densidade 7,5. É geralmente encontrada em companhia de quartzo, esfalerita e fluorita. The most common sulfide crystalling in this manner is galena (PbS), the ore mineral of lead. A type of packing that involves two sulfide ions in each of the octahedral positions in the sodium chloride structure is the pyrite structure. This is a high-symmetry structure characteristic of the iron sulfide, pyrite (FeS 2 O).
